Questions about PHAT

What people ask.

Why is PHAT on Broken Stocks?

PHAT qualifies for the Red List on decline depth. It is down -53.0% from its rolling 252-day high of $18.31, set on 2025-12-23 — 240d ago.

Is PHAT a falling knife?

Not by the strict technical definition. PHAT is down -53.0% from its 52-week high, but that high was set 240d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. PHAT is still on the Red List for decline depth, but the freshness component of a falling knife is missing.

Is PHAT a buy?

Broken Stocks does not issue buy or sell recommendations. The list is a rules-based technical warning system. It tracks structural decline depth and recency — not company quality, management, fundamentals, or news. Always do your own research and consult a licensed advisor.

Where is PHAT trading inside its 52-week range?

At $8.60, PHAT sits 5.6% of the way from its 52-week low ($8.03) to its 52-week high ($18.31). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has PHAT been declining?

The current 53.0% decline accrued over 240d, which annualizes to roughly -80.6% per year. Annualized pace is a sanity check — a 30% decline in three months is a different signal than a 30% decline over two years.

How does PHAT compare to its sector?

There are 143 other Healthcare tickers on Broken Stocks: 69 Red, 35 Amber, 39 Watch, with 50 showing recovering structural signals. Median sector decline is -36.1% — PHAT's decline is deeper than the sector median.

Does PHAT's earnings date affect its tier?

No. Tiering is decided purely by decline depth and recency of the rolling-high date. The earnings date on file (2026-07-30) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
